I've rode them all, I think my elkas rode the best, that being said, they were custom valved for me where everything else was the standard out of the box valving. Coils regardless of brand tend to be a hair more plush then the airs no matter what fancy coatings etc fox has. But the airs and QS3 offered the most end user adjustment.
The one demise of elka is there is a LOT of steel parts. steel caps, etc, non lightweight coils etc. 5/8" shafts. I do think the bigger shafts and overall more mass made for better heat dissipation as I NEVER had those fade where I have faded some fox stuff. But kinetics and burandt airs are both close to half the weight of the elkas. So take that into consideration.
Only thing I hated and reason i gave up on elka was being in the states it was virtually impossible to get parts or service from elka and I know others that have had the same issues. The support was incredibly sub par and made me head new directions. My last setup I rode was the Fox burandt airs and I've been rather please with those. The QS3 feature is probably my favorite and why I've been most happy with the Fox package. overall most user friendly combo that I actually adjust day to day.
